When it comes to overclocking your system, the video card tends to be the easiest component to tinker with. To overclock your CPU, you need to take into account the litany of components such an operation would affect. With a video card, as long as you have the right software it can be as easy as just incrementally bumping up the core and memory speed until the card reaches it’s limits of error-free functionality. This normally requires you to close whatever application you may be running in order to launch a separate program for this tweaking. ZOTAC has done away with this step with their NITRO VGA Overclocking Controller.
